How many values of x with 0 degrees <= x <= 2500 degrees satisfy sin x = -0.31?
sin x = -0.31
x ≈ -18
First angle = 180 + 18 ≈ 198°
Second angle = 360 - 18 = 342°
Nunber of full rotations in 2500° = 2500/360 ≈ 6.94
(.94) * 360 ≈ 339°
So there will be 6(2) + 1 = 13 values of x that satisfy sin x = -.031
